Study Area Ø Case study area, Mone Chaung Dam in Magway region which is one of the most affected region of flood damage in Myanmar. Ø It is situated on Middle West region of Myanmar and built across on Mone creek. Ø Mone creek can be overflow water due to torrential rain from Chin hill and Rakhine hill.

Conditions of Flood in Mone Chaung Dam

Conditions of Flood in Mone Chaung Dam

Mone Chaung Dam Ø Mone Chaung Dam is situated in Magway region and it is very mountainous area. Ø The other dam (Kyee-on Kyee-wa) is situated on low lying area and if it will break or overflow water, affect on about 300 villages and two towns in that region. Ø Its alarm level is 540' and Dam crack level is 560'.

Conclusion Ø Flood is one of the most crucial disasters all over the world. Ø Flood management system is important factor to prevent, control and reduce of damage hazard. Ø This presentation intends to know about the case study of flood conditions in Myanmar and propose the flood prediction system Ø It will provide to inform people living in low laying area of Mone Chaung Dam to take precaution before facing the flood.
